Connecting Operations In Part Design | Modelling a Mug | Basic Beginners FreeCAD 0.22 Lesson 12
HTML-код
- Опубликовано: 12 сен 2024
- This FreeCAD tutorial we'll expand how to connect operations across multiple planes and profiles. This guide is perfect for beginners, offering a gentle introduction to FreeCAD's sketch attachment mode. You'll learn a simple trick to create a thickened surface with single open outline in the Sketcher, making your modeling faster.
What You Will Learn:
In this lesson, we'll cover the following FreeCAD operations at a beginner level:
Part Design:
* Revolve: Learn how to create revolved shapes for complex designs. We will use this for the cup.
* Sweep / Additive Pipe: Understand how to use the sweep feature to create intricate pipes for a supplied profiles. We will use this for the handle.
* Sketch Attachment Mode: Discover how to attach sketches to existing edges, vertices, or points for precise placement.
* Fillet: See why a fillet might fail and fix the problem.
Sketcher:
* Offset: Learn to quickly create a closed wire within your sketch for an open one.
* Import Geometry: Find out how to import existing geometry into a new sketch for accurate modeling.
* Fillet: Smooth out sharp edges in your sketches with the fillet tool.
* Construction Geometry: Use construction lines to guide your sketching without affecting the final model.

These videos are freakishly valuable in calibrating intuition about freecad and cad in general!
Thank you so much :) There is not much out there with explaining from a capture perspective of how to get real things into CAD. Glad to see your enjoying :)
Awesome video as usual. The pace in your videos is perfect. Slow enough to make them easy to follow but at the same time quick enough to not to be boring.
Thank you so much for the feedback, always helps. From the feedback from the previous series I have shortened them a bit and tried to separate out more of the theory into other videos. So I am always tweaking the videos to find a happy medium. Glad you enjoyed.
Great Lesson, can't wait for the stable 0.22 version. Bugs surprise me at times, wont select axis, or the ubiquitous "access violation"... But I improvise. Thanks for the great videos, I appreciate all the effort you put into these, and the level of explanation, the repetition will solidify the toobar icons and their use. Even though they sprang new ones in 0.22... Thanks to your great videos, I am able to draw and print my own objects. Sometimes I get an idea on Thingiverse, but it needs modification, well, you have provided enough instruction its fairly easy to modify or just redraw... Thanks
Glad your enjoying these lessons and so glad they have helped you to model and customize existing ones by rebuilding them. It's one thing coming up with an idea but so frustrating when you can't put that into something that can be crafted. One of the reasons why I made these videos. 0.22 is getting better, they still have a number of bugs in the list to fix but it's coming down.
Congrats at making the FreeCAD blog. Nice shout out to your channel.
Thanks so much! It was so nice surprise when I opened up twitter and found that post. I had a peak in subscribers and I was trying to figure out where they came from.
Thank you !
I've been using FC for over 10 years. So many things have been added that I don't know about. The new dimension tool just pissed me off until now. Didn't know I could attach a sketch to the end of the other one like that. Just wow, it's a whole new Freecad to me. I've been fighting things through like I did 10 years ago
Thank you for another great lesson
My pleasure! :) :) :)
I never realized you can use attachment references that way, today I learned
It's a very powerful tool, I do have a video dedicated to it if it helps. Hopefully YT won't remove this link ruclips.net/video/jfhgcDcAAlk/видео.html
As always a clear and comprehensive explanation of everything You do... I just wish that F.C was as reliable ;)
Best regards,
Thanks :) glad you enjoyed. Hopefully it will become more stable as time goes on.
Tell you what I would love MJ, to be able to click a point, then press constrain XY - with the result that it constrains that position to the origin in both dimensions with a single mouse click!
Then, if we could set a new datum point, say, the last constraint, another function would set any future selections to that new origin...
This would save soo much time!
Ah...so.... there is the constraint 'constraint lock' that adds both a X and Y constraint for the selected point to the origin which may help with the first one. The second one, you can do the same but select two points with the constraint lock and it will offset from that point. But I don't think you can select a new point and say that this is now the new origin (I had a double check but couldn't find anything. I for one would find this extremely useful). The only thing with the constraint lock is that you get a minus value depending on what side you constrain from. Not a issue but something to remember if your using things like formulas and spreadsheets.
great tutorial! How would you alter the model if the lower end of the handle ends in the slanted part of the mug. I would make that it stick out to the inside and then delete the face or make a revole cut in the cup, but this feels somehow not perfect.
I was thinking exactly the same question. I would reverse the operation order: first make the handle, then subtract a solid revolve from the midprofile of the mug, and then add the mug revolve. I would love to hear from MJ what would be his approach in this situation.
Thanks glad your enjoyed, yes your way and @dmmgualb are perfectly good enough, but as with everything, always another way. Depending on how large the handle profile is you can include additional profiles into the pipe so it become a multi profile operation. So you can have a beginning and an end profile. This can be a simple duplication of the last sketch and attached with the map mode to the other end of the path. The key here is to use the rotate around axis in the sketch attachment panel when using the map mode and rotate it so its parallel to the slant. You include both profiles in the pipe operations and you get something that fits the surface.
Any idea when 0.22 is being released?
Can you create a bike frame in your future videos? Thanks!
It's nice that you can make it through this tutorial using .22 😂 Revision 38553 won't let me apply _equal_ constraints to the fillets for some reason. I guess I ought to file a bug report?
Never mind. I started the sketch over and now it works. This time I spoke softly to my monitor while applying the fillets. I think that helped.
Helllo, for some reason i cant find the offset? I'm on 0.21.2
These videos are for version 0.22 dev version of freeCAD which is downloadable from the weekly builds. The offset tool is new to 0.22.
I have installed Python 3.12 on my windows 7 computer. Early Freecad 0.22.0dev versions worked fine and now latest versions won't work properly and tells me so many DLL files missing.. Not sure what is causing this problem as python is working fine.
Hi, Darren,
Where i can download Freecad Version 0.22 for windows 11?
My best regards.
Meh, version 1 isn't available at the moment. Shame
